Main Question or Discussion Point
Assuming the higgs field expands at the speed of light, the radius of the higgs field (all of spacetime actually) should be the age of the universe multiplied by the speed of light. 14.6 billion (4.6*10^17 seconds) * 299,792,458 m/s = 1.38 * 10^26 meters. The spherical volume of spacetime is going to be even larger, so my question is where does the energy come from to expand? The higgs field can be excited to make the higgs boson so it must have energy, but the endless expansion of spacetime, and the higgs field, seems like it violates conservation of energy, and does so at exponential rates because of volume. Shouldn't the higgs field decrease in strength over time?
